Screwdriver bit set with identification functions

Abstract

The present invention provides a screwdriver bit set with identification functions. Each bit body in the set has an insertion end, an actuating end and a neck portion. An aluminum alloy identification ring includes a trepan boring for assembly onto the neck portion of the bit body. The aluminum alloy identification ring also has an outer ring surface protruding from the neck portion of the bit body. An anodized protective film is formed on the surface of the aluminum alloy identification ring. The protective film presents bright color and a corrosion-resistant property, helping to prevent discoloring and provide durable identification effects with improved applicability.

1. A bit assembly having an identification function, the bit assembly comprising:
 a body having an insertion end and an actuating end with a neck portion extending between said actuating end and said insertion end, said neck portion having a polygonal cross-section; 
 an aluminum alloy identification ring having a circular boring extending therethrough, said ring affixed onto said neck portion of said bit body such that edges of said polygonal cross-section tightly embed with an inner wall of said ring, said ring having an outer ring surface protruding from said neck portion; and 
 an anodized protective film formed on said outer ring surface of said ring, said protective film having a bright color, said protective film being corrosion-resistant.
